Not sure, but open weights have had their effects. For example, look at Wan 2.2 the last open weights Wan release, still the most powerful Video inference out there, to the level of quality it provides, unfortunately, it went closed source, but before they did, the community had built all sorts of tooling and LoRas on top of it. Nothing comes close for video a year later. Back to llama though, look at all the open models people run offline through their Macs. It definitely had a net positive.
